1 Claim.

This invention relates to improvements in coffee pots, and moreparticularly to drip coflee pots.

One object of this invention is to provide an improved drip coffee potin which the waterand-coffee unit can be housed in the pot with thecover in proper position when the coffee pot is not in use.

Another object of this invention is to provide an improved drip, coffeepot in which the-waterand-coffee unit can be withdrawn from the coffeepot and rested upon the upper portion thereof during the making ofcoifee by the drip process.

Another object of this invention is to provide an improved drip cofleepot in which the waterand-coffee unit can be entirely removed from thecoffee pot, and the cover placed in proper position on the pot forserving coffee.

With the above and other objects in view, this invention includes theimproved features, parts and combinati of parts disclosed in thefollowing description, appended claim and accompanying drawing forming apart of this specification.

In the accompanying drawing, in which one way of carrying out theinvention is shown for illustrative purposes:

Fig. 1 is a vertical, central, sectional view illustrating the entirecoffee pot construction in assembled relation, for storing when not inuse;

Fig. 2 is a transverse, sectional view on line 2--2 of Fig. 1;

Fig. 3 is a transverse, sectional view on line 3-3 of Fig. 1; 1

Fig. 4 is a perspective view of the water-container;

Fig. 5 is a perspective view of the coffee-container which, togetherwith the water-container, forms a water-and-coffee unit;

Fig. 6 is a top plan view of the outer or main pot alone; and

Fig. 7 is a vertical, central, sectional view showing thewater-and-coifee unit supported on the upper edge of the main pot, inthe position it occupies while drip coffee is being made.

Referring to the drawing, i0 is the outer or main pot having the pouringspout l I and handle l2. The inturned flange l3 at the' top of the mainpot is'provided with notches or cut-out portions ll for a purpose to bepresently described.

A water-container I5 is provided with a plurality of pressed-out,longitudinally-extending ribs 16, the number and spacing thereof beingsuch as to permit their being aligned with the (Cl. 5H)

notches ll, to permit the water-container 15 to be slid longitudinallyinto and out of the main pot.

The lower end ll of the water-container I5 is provided with drip-holesl8 for the passage of 5 water, and with bayonet-slots l9. Acofiee-container 20 is provided with cofiee drip-holes 2| in the bottomthereof and with pressed-in lugs 22, the number and spacing of which isarranged to suit the bayonet-slots i9, so that the coffee-container 20may be readily placed in assembled relation with the water-container l5by means of the lugs 22 and bayonet-slots IS, in a manner that will bereadily understood. Instead of usin a bayonet-slot type of construction,any other 15 suitable construction for detachably connecting thewaterand coffee-containers together may be used such, for example, as ascrew-thread fit, or a friction fit.

The waterand coffee-containers constitute the water-and-coffee unit 23.when the device is to be stored or shipped, the water-and-cofiee unit 23is arranged in suitable rotative position to bring the ribs IS inalignment with the notches [4,

whereupon the water-and-cofiee unit will slide 5 downward until it restsupon the bottom of the mainpot Ill, whereupon the cover 24 of the pot isplaced in its properly-fitted position upon the main pot, all as shownin Figs. 1 and 2.

when coflee is to be made, the cover 24 and 30 coffee-unit 23 areremoved from the main pot Ill, whereupon the coifee-container 20 isrotated in the proper direction to disconnect the lugs 22 from thebayonet-slots l9, whereupon the cofieecontainer 20 becomes separatedfrom the watercontainer i5. Ground coifee is then placed in thecup-shaped coffee-container 20, whereupon the latter is connected in itsassembled relation with the water-container I5 to form thewater-andcofiee unit 23, which latter is then placed on 40 the top ofthe main pot III in such rotative position, as for example, with theribs in the position indicated in broken lines at l5 (Fig. 2), out ofline with the notches I4, thus causing the bottom-end surfaces 25 of theribs It to rest upon the inturned flange l3 of the main pct 10, as shownin Fig. 7.

Hot water is now poured'into the water-container l5, whereupon it dripsslowly through the holes l8 onto the ground coifee in thecoffeecontainer 20, and thence on through the holes 2| and into thebottom of the main pot l0.

After the drip process has been completed to satisfactorily make thecoffee as desired, the water-and-coffee unit 23 is lifted oif oi themain 24 will be placed in its normal proper position, as shown in. Fig.l, with the coffee pot containing the prepared coffee liquid ready forserving, and,

of course, with the water-and-coflee unit 23 out of and away from themain pot III, as has previously been described.

- After the parts or the cofiee not have been cleaned, the waterandcofiee-containers are again assembled to form the water-and-coflee unit23, which is placed inthe proper rotative position to permit it to bringthe ribs l8 and notches H in alignment, whereupon the waterand-cofl'eeunit can he slid downwardly so as to be mainly housed in the main potl0, after which the cover 24 is placed in position, all as shown in Fig.l.

The invention may be carried out in other specific ways than that hereinset forth without de parting from the spirit and essentialcharacteristics of the invention, and the present embodiment istherefore to be considered in all respects as illustrative and notrestrictive, and all changes coming within the meaning and equivalencyrange of the appended claim are intended to be embraced therein.

I claim:

A drip coflee pot including: a main pot having a limit flange, and areduced upper end connected to said limit flange and provided with aninturned flange, said inturned flange being provided with one or morenotches; and a. waterand-cofiee unit including a water-container, and acofiee-container detachably connectable to said water-container; saidunit having one or more longitudinal ribs slidably interengageable withsaid notches in one or more rotative positions but not in certain otherrotative positions, to permit said unit to'alternatively be mainlyhoused within, or supported by and mainly above and outside of, saidmain pot; and a cover detachably fitting down over said upper end ofsaid main pot and down beyond said intumed flange and adapted toproperly slidably flt down over said reduced upper end and engageagainst said limit flange when said unit is in its mainly housedposition in said main pot.
